Stayed as an extended family group of 9 people and had a fantastic time! The barn was huge and plenty big enough for our group with six double/twin rooms most of which had en-suite bathrooms. The bedrooms were tastefully decorated and well appointed and the communal space was more than adequate. Outside the grounds were large and blended seemlessly with the owners' garden.
The house is set in a relatively isolated location which we enjoyed but you can be at Lake Balaton within about 20 mins or so.
